WILLIAMS ETAL AUTOMATIC PRESS 5 Shets-$heet 5 Patented Nov. 10, 1942 UNITED STATES: PATENT OFFICE nati, Ohio, assignors toThe American Laundry Machinery Company, Norvvoo'd, Ohio, afcorpo ration of Ohio Application October 21, 1940, Serial No. aisaosp 14 Claims This invention relates to improvements in pressing machines designed especially for pressing small flat articles such as handkerchiefs, napkins and the like, although many of the features of our improved press are useful for other purposes.

An object of the present invention is to provide an improved press of the turret type having a single stationary heated ironing head and a pair of beds or bucks movable by rotation of a turret frame from a dressing position in front of 'the operator to a pressing position beneath the heated head. Our invention provides improved automatic mechanism for rotating the turret frame, for causing pressing engagement of the head and bed and for timing the pressing operation. Other features include improved means for clamping a workpiece on the bed for a smoothing or dressing operation, manual control of the automatic mechanism when desired, and improvements in the operating and control mechanism as will appear from the accompanying specification and drawings. V

The machine r d sc o ed. com ri es a ma frame having a base member In side walls I l and a top frame casting I2 Mounted on the top frame casting are two rear posts l3 and a forward post l4 about which the turret frame re volves. These three posts support a stationary head which may be heated in any suitable or usual manner. The post I4 as best seen in Fig. 5 centers a turret frame bracket l6 which is supported on a suitable bearing I! in the frame 53 24a is in proper position above the rod 21.

casing I2. A turret frame I! is mounted on the member I6 and extends in diametrically opposite directions for the support of a pair of pressing beds l8 and I9. Obviously, upon rotation of the turret frame onerof the beds is'carried into pressing position beneath the head l5 while the other bed is in dressing position in frontof an operator.

Improved clamping means is provided for holding the rear, edge of an article, such as a napkin or handkerchief, while the operator smooths the article on the pressing bed. This mechanism comprises two clamps 20, one for each bed and exactly alike so that one only need be described. Referring to Figs. 1, 5 and 6, each clamp extends substantially the entire Width of its associated bed and is pivotally mounted by arms 2| on a pair of brackets 22 supported by the turret frame. A link 2.3. connects one of the arms 2| with a lever 24 which ispivotally supported at 25 by a bracket mounted on the turret frame. A spring 26 normally biases the clampsaway from clamping position as shown in full lines in Figs. 1 and 6. An arcuate plate. 24a is provided on the bottornof each lever 24 for engagement of the clamp actuating mechanism. Only one mechanism is provided and this comprises a rod 21- mounted for vertical movement in a block 28 and normally held in position to engage against one of the plates 24a associated with the clamp for that pressing bed which is in the forward or dressing position. The rod 27 is, normally biased downwardly by a spring 29 held between the block 28 and a collar on rod 21. A pedal 30 carried by the frame is actuated by the foot of the operator to cause movement of a clamp to the dot-dash position of Figs. 1 and'6 when the operator desires to dress an article on the bedbefore her. The block 28 is so mounted as to take care of accidental operation of the pedal 30 before one of the clamp actuating plates To this end the block 28 is movable horizontally between flanges 3| and the block is normally'heldin its r'earmost position as indicated in full lines in Fig. 6"by'a spring 32. If the rod 21 has been elevated by the operator before a pressing bed reaches proper position before her, the lever 24 will kick the rod 21 to the forward dash line position indicated in Fig. 6. The operator will then release the pedal 30 to return the rod to the full line position of Fig. 6 ready to perform the proper clamping operation as indicated by the dot-dash lines "of that view; The means provided for rotating the turret frame comprises a lever 33 which is rotatably mounted upon a stub shaft 34 carried by a bracket 35 which is mounted on the top frame casting I2. The lever 33 has an upstanding branch 33:]. adapted to engage one of two projections 36 on the turret frame as will be presently described. The lever 33 has a downwardly extending branch 332) which is pivotally connected with the piston rod 31a of motor 31 whose cylinder 31b is pivotally mounted in the frame at 38. Another branch 330 of lever 33 is engaged by a pair of springs 39 which are connected to the main frame in a manner to bias the lever 33 in a counterclockwise direction as viewed in Fig. 2. A shock pad 40 on bracket 35 limits the movement of lever 33 in one direction and an adjustable screw or stop 4| limits its movement in the opposite direction. As best seen in Fig. 8 the upper end of lever arm 33a carries a spring pressed plunger 42 adapted to pass by the projection 36 when moving in one direction and adapted to engage that projection to turn the turret frame in the opposite direction. Also on the upper end of lever arm 33a is a pair of cars 43 between which is mounted a latch pin 44. When the motor 31 has moved the lever 33 clockwise from the position of Fig. 2 to the position shown in Fig. 3, the pin 44 engages behind a latch 45. This latch has an arm 45a which is connected by spring 46 to the frame so as to bias the latch 45 in an upward direction. A stop 41 limits this latch movement. A block 48 connected with latch 45 lies beneath a pin 49 of the bed in pressing position so that when that bed moves downwardly out of pressing position the pin 49 will engage the block 48 and release the latch 45 so that the turret frame may be rotated by the springs 39 acting on lever arm 33c which engages the projection 36 of the turret frame.

The beds l8 and I9 are each mounted for vertical movement relative to the turret frame l1. Each bed normally rests upon the turret frame on four corner posts 50. A pin connected with the bed extends downwardly through a guiding bracket 52 in the turret frame. Another bracket 53 serves to guide the pin 49 and a spring 54 normally urges the pin and bed downwardly at this point. At the end of each bed toward the central post I4 is provided a flat leaf spring 55, which as best seen in Fig. 5 extends transversely of the bed and is connected at one end to the turret frame and at the other end to a boss 55a. This anchors the end of the bed to which it is attached and also helps to urge the bed downwardly out of pressing engagement with the head l5. Each bed in its central portion is. provided with a downwardly extending bracket 56 adapted to be engaged by the actuating member ofa motor 51 which is provided to cause pressing engagement between the head l5 and a bed in registry beneath it.

Means is provided for snubbing the movement of the turret frame as a bed moves into registration beneath the pressing head. One such means comprises a lever 58 connected to an air check cylinder 59. The lever 58 as shown in Figs. 1 and 2 is mounted on a stub shaft 60 which is carried by bracket 35. The upper end of this arm is connected by rod 6| to the piston of the air check 59. Exhaust from the air check is controlled by adjustable valve 62. The upper end of lever 58 carries a pin 63 which is adapted to be engaged by pin 5| as the turret frame moves to carry a bed into pressing position. This moves the lever 58 from the position shown in Fig. 3 to that shown in Fig. 2 so that the air check provides the desired snubbing action. When leverarm 33a moves in a clockwise direction as seen in Figs. 2 and 3, a lug 64 carried by lever arm 33a engages pin 63 so as to return lever 58 to the position of Fig. 3 ready for its next snubbing operation. Additional means for providing snubbing action of the rotating frame and for holding the bed in registered position beneath the pressing head is best seen in Fig. 4. Here a lever 65 is pivotally mounted at 66 on the main frame for movement in a horizontal direction. This lever has a curved face 65a eccentric to the path of movement of the pins 5! as the turret frame revolves. The lever 65 is biased to the position shown in Fig. 4 by a spring 61 which is controlled by an adjusting screw 68 mounted in a bracket in the frame. Thus as one of the beds moves to registration position the pin 5| cams the lever 65 downwardly as viewed in Fig. 4 providing additional snubbing action to frame movement until pin 5| moves into notch 69 of lever 65 to hold the bed in registering position. A stop 19 on the frame limits the movement of lever 65.

Means is provided for moving a bed in registering position into pressure engagement with the head l5. This means comprises the motor 51 previously described whose cylinder 51a. is mounted on the frame member l2. A piston 51b is normally biased downwardly by a spring 510 and is provided with a piston rod 51d adapted to engage against the bracket 56 of a bed directly above it. Pressure fluid is supplied to this motor as best seen in Fig. 9 from a supply conduit 1| through an operator controlled valve 12, conduit 13, a valve 14 controlled by turret frame rotation, conduit 15, valve 16 controlled by a timer, and conduit 11. Valve 16 is normally open as shown in Fig. 9 and its operation by the timer will be later described. Valve 14 is normally closed and is opened by movement of a pressing bed into registration position beneath the pressing head I5. The means provided for accomplishing this includes a spring pressed plunger 18 pivotally mounted at 19 on a bracket connected with the frame. A rotatable follower 88' on the plunger mechanism is engaged by a finger 8| as a bed reaches registering position. It will be noted in Fig. 1 that there are two of these fingers, one located beneath each bed on the turret frame.

The timer mechanism as best seen in Fig. 9 comprises a reservoir 82 adapted to be filled with pressure fluid through the branch 11a of conduit 11 which leads to a needle control valve 83 located within reach of the operator and thence by Way of conduit 84 to the reservoir 82. The upper end of this reservoir is closed by a diaphragm 85 which is adapted to move upwardly and engage a stem 86 which in turn is adapted to lift valve 81 from its seat when the lifting force overcomes the pressure in the diaphragm chamber 88 which acts through spring 89 to hold valve 81 normally upon its seat. The diaphragm chamber 88 is supplied through branch conduit 13a from the main pressure fluid supply. The outlet from reservoir 82 is by way of valve 99 which is held against its seat by spring 9| and the pressure against the valve disk from below exerted through the branch conduit 11b. The valve 83 is for the purpose of adjusting the flow of air to reservoir 82 so as to vary the time interval required to open valve 81. This valve 83 is adjustable by means of manual 92 which is within easy reach of the operator. Preferably easily adjusted settings are provided for timing l b? operation of the pressing machine to accommodate the articles normally being handled; For instance one setting maybe for a light.article such as handkerchiefs, and another settin for. heavier articles such asnapkins which would require a longer period. To this enda pair of collars 93 and 94 are provided on the valve casing for valve 83 as shown in Figs. 7 and 9. These collars have stop pins 93a and 94a respectively, the position of which is adjustably fixed by means of set screws such as that. shown at 95. The manual, has an arm 92a which is shown in the twoviews as resting'against the stop pin 93a for a setting say for heavier articles, such as napkins. By rotating the hand wheel or manual 92 clockwise as viewed. in Fig. '7 until the arm 92a engages the stop pin 940,, the setting is quickly changed for light-weight articles such as handkerchiefs.

The timer mechanism is adapted to discontinue the pressing operation when valve 81 is lifted from its seat. purpose includes a conduit 95 leading by way of check valve 96 and a. small reservoir 91 to diaphragm chamber 98. Pressure fluid acting through this diaphragm chamber causes normall-y open valve 16 to, close thus interrupting communication between conduits l1 and 15 and connecting conduit 1-! to the exhaust at 99. An adjustable bleed valve. I communicates with conduit. 95.

Means is provided for manually causing termination of pressing engagement between two pressing members and associated with the valve [2. This valve has a manual 12a located handy to the operator. line position of Fig. 9 the press has a continuous automatic, operation. When the manual is moved about its eccentric mounting to the dot-dash line position of Fig. 9, valve, 12 isv held against the seat 121) so as to provide communication between conduit 13. and conduit IOI which leads to, diaphragm chamber '98.

Operation When the parts are in the position of Figs. 1 and 2, it is assumed that the manual 12a has been raised to the dash-dot position of Fig. 9 which has caused the bed in registration with head l to move downwardly out of engagement with the head after which the turret frame is revolved bringing the other bed into registration position where it remains. To begin auto- When this manual is in its full 5 The mechanism for this I matic operation, the manual 12a is moved to the full line position of Fig. 9. This permits valve 12 to move toward the right under influence of its spring permitting flow of pressure fluid from supply conduit II to conduit [3 and valve 14. Since the turret frame is in position registering bed l8 with the head l5, one of the fingers 8| is in engagement with the spring plunger mechanism l8 and valve 14 is open. This permits flow of pressure fluid through conduit 15, normally open valve 16 and conduit 11 to motor 51 which causes an upward stroke of piston 51b and raises bed l8 into pressing engagement with the head I5. At the same time a branch conduit 11c conducts pressure fluid to motor 31 so as to move lever arm 33a to its cooked and latched position shown in Fig. 3. It will be noted in Fig. 3 that the movement of pin 5| upwardly as bed l8 engages head l5, releases lever 58 so that lever arm 33a may carry it. toward the right at this time.

Simultaneously with the energization of motors 51 and 31, air pressure travels through the branch Ha, valve 83 and conduit 84 to the timer reservoir 82 and begins to build up pressure in that reservoir. In the meantime the operator has: grasped another article from thetray I02 before her for dressing on the bed; in the open position. In making the lay she picks up the article by one edge and lays it out toward the rear of the bed l9. She then depresses the pedal 30 which elevatesrod 21 and causes clamp 20 to move to the dot-dash position of Fig. 1 thus clamping the rear edge of the article securely to the bed. She then smooths the article. out toward the remaining three sides and releases the pedal which permits the clamping bar to. return to the normal position shown in full lines in Fig. 1.

When the pressure in timer reservoir 82 builds up to the point where the force acting upwardly on diaphragm 85 overcomes the force exerted by diaphragm chamber 88, valve 81 is opened, thus releasing pressure fluid to the diaphragm chamber 98 and moving valve 16 dawnwardly as shown in Fig. 9. This shuts off all pressure fluid flowing through conduits I5 and 71 and opens conduit H to the exhaust at 99. This exhausts motors 51 and 31 and cuts off fluid flow to the timer re-.

servoir 82. The release of pressure below valve of the timer causes a sudden exhaust of pressure fluid from reservoir 82. Evacuation of mo. tor 5'! permits the bed I8 to lower out of pressure engagement with the head. This downward movement by means of pin 49 disengages latch 45 from pin 44 which releases lever 33 to the action of springs 39. The lever arm 33a by engagement of the projection 36 then causes the turret frame to be rotated carrying bed l8 out of pressing position and bed l9 into pressing position.

As the turret frame begins to move the plunger mechanism 18 swings away from the stem of valve 14 so that this valve closes under the influence of its spring. This cuts off the supply to valve 16 so that when this valve again opens it is not supplied with air until another bed reaches registering position. Air is supplied to the diaphragm chamber 98 only so long as valve 81 is open. This is a comparatively short time but is long enough to provide evacuation of the system. However to insure full evacuation the small reservoir 91 has been provided. This stores just enough pressure fluid to hold the valve 16 closed a short interval after valve 8'! closes. This provides additional time which insures full evacuation of the system. The pressure fluid from diaphragm chamber 98 slowly bleeds off through valve I90.

If the article which the operator has just dressed on bed 19 in front of her is, of different texture than the previous one, as the frame begins, to revolve she makes the necessary adjustment of the regulating valve 83 by means of the manual 92. As bed I!) comes into registration with head I5, the pin 5| beneath bed l9 engages pin 63 of lever 58, rotating this lever against the action of the air check 59. At about the same time this post also engages the cam surface 65a of the lever 55. The combined effect is to check or snub the movement of the turret frame until the post 5| lodges in the notch 69. The valve 14 is again opened and the operation. as above described is repeated. It should be noted that with the parts in the position of Fig. 4 when the turret frame begins to rotate to change the position of the beds, the rod 5! cams the lever 65 downwardly so as to permit rod 5| to move out of the notch 69.

Should the operator for any reason desire to cause disengagement of the pressing members other than by operation of the timer, she raises the manual 72a to the dot-dash position of Fig. 9. This moves valve 72 against the seat 12b and establishes communication between conduits l3 and HH. There is sufficient back pressure in the system connected with conduit 13 to flll diaphragm chamber 98 and cause opening of the pressure members as previously described in con nection with the timer operation. The registering bed will therefore move out of engagement and the turret frame will be revolved for another operation.
